Abstract
The study was carried out to assess whether continuous lighting (CL) can be used to reduce nitrate content in Brassicaceae microgreens. Arugula ( Eruca vesicaria subsp. sativa ), broccoli ( Brassica oleracea var. italic ), mizuna ( Brassica rapa var. nipposinica ) and radish ( Raphanus sativus var. radicula ) seedlings were grown in the controlled climate chambers under 16 h or 24 h photoperiod provided by light-emitting diode (LED) or fluorescent (FLU) lamps. At the pre-harvest stage, half of microgreens were treated by CL for 3 days. The results show that nitrogen content was decreased significantly in plants grown under LED CL compared to plants grown under 16 h photoperiod. The highest decrease (by 40 %) was observed in arugula microgreens. In contrast, CL provided by FLU lamps had little effect (decrease by 11 and 6 %) on nitrate content in mizuna and broccoli and no effect in arugula and radish. Pre-harvest treatment by CL resulted in significant decrease of nitrate content in all four plant species. In conclusion, continuous LED lighting applied during microgreen cultivation or at the pre-harvest stage effectively reduces nitrate content in Brassicaceae microgreens.
